How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Screw pin shackle | The bolt-type shackle has a more secure closure under vibration and does not require a cotter pin, but is slightly heavier and less compact |
| Safety pin shackle | The bolt-type version allows for easier inspection and re-tightening without removing a cotter pin, but requires a wrench for closure |
| Soft shackle | The steel version handles abrasion and high loads better than a soft shackle, but is heavier and less flexible |
| Rigid shackle | The bolt-type version allows for easier disassembly and inspection, but is not suitable for applications requiring a permanent connection |
Use Guide
How To Use And Inspect Shackle Anchor
- Verify the stamped working load limit matches the calculated load, not the equipment rating
- Ensure the bolt is fully tightened with a wrench and the nut is secure before loading
- Inspect the shackle for deformation, wear, or finish damage before each use
- Do not use if the bolt or body shows signs of cracking or plastic deformation
- Avoid side loading the shackle; keep the load aligned with the bow axis
- Retire the shackle if the marking is illegible, the bolt is stripped, or the finish is compromised
